Release agent-guidelines 0.0.30

[backslash-f]

Summary

• document that Swift packages retain their root LICENSE and standard license badge without a dedicated README License section
• make consumer setup validation reject dedicated ATX or Setext License headings and conventional standalone license prose only for root Swift package READMEs
• preserve badges, ordinary inline references, missing READMEs, fenced examples, vendored guidance, and non-package documentation
• prepare release 0.0.30 by updating VERSION, both README subtree commands, and the changelog

Review history

• initial exact-head Reasoning Relay review found nested-fence and Setext-heading P1 gaps
• both gaps were remediated and the follow-up exact-head delta review approved the implementation with no unresolved P0/P1 blockers
• release metadata changes require a final review at the current exact head before merge and publication
